摘要：为探寻在有机种植管理模式下适宜的种植密度和有机肥施用量，在湖南省郴州市桂阳县烟叶生产基地进行了不同种植密度的两因素随机区组试验（株距和行距两因素各3个水平）以及有机肥不同施用量的单因素随机区组试验（233.33、300、366.67 kg/667m2），通过逐步回归分析，筛选出烤后烟叶理化指标处在较适值的试验处理。结果表明，株行距为0.5

m×1.2 m、0.6 m×1.1 m的烤后烟叶理化指标较适宜，有机肥施用量在300.62～355.13 kg/667m2的烤后烟叶理化指标处于较优范围。

Abstract：Tworandom block experiments were conducted to investigate the effects of main organic cultivation technologies， including different application rates of organic fertilizers

（233.33， 300 and 366.67 kg/667m2） and different planting density （three levels respectively for plant and row spacing）. Stepwise regression analysis was used to screenthe experiment treatment in which the physical characteristics and chemical components of strong aroma tobacco being at optimum values. The results showed that better physical characteristics and chemical componentswere obtained when the planting density had the space collocation of 0.5 m×1.2 m and0.6 m×1.1 m， and the organic fertilizing rates were within the range of 300.62-355.13 kg/667m2.
